URL: https://issues.apache.org/jira/browse/IOTDB-802
Project: Apache IoTDB
Issue Type: Improvement
Components: Core/Engine
Reporter: Yuan Tian
Assignee: Yuan Tian
If there exits same series in different aggregation function of one query, in
0.10, we only need to read the data once and apply different aggregate function
to it.
However, the batch data we cache for each series, we need to reset its cursor
to zero every time we apply another new aggregate function to it. It will cause
needless next() call.
We should only reset the cursor to the last read position instead of zero.
